Table 5.
Logistic regression analyses regarding the association between the dependent variable dementia and the independent variables birth cohort, sex, education and stroke, and different interaction terms.
| Independent variables | Model 1 | Model 2 | Model 3 | Model 4 |
|---|---|---|---|---|
| OR (95%-CI) | OR (95%-CI) | OR (95%-CI) | OR (95%-CI) | |
| Birth cohort | 0.66 (0.50–0.86) | 0.90 (0.66–1.22) | 0.81 (0.59–1.11) | 0.98 (0.68–1.41) |
| Male sex | 0.81 (0.59–1.1) | 0.79 (0.57–1.09) | 0.80 (0.58–1.11) | |
| More than basic education | 0.70 (0.51–0.97) | 0.69 (0.50–0.95) | 0.70 (0.51–0.96) | |
| Stroke | 2.52 (1.82–3.49) | 3.78 (2.28–6.29) | ||
| Stroke*birth cohort | 0.50 (0.26–0.97) |
Dementia is dependent variable in all analyses.
Interaction terms education*birth cohort (p = 0.63) and education*stroke (p = 0.97) were not significant and therefore removed from the models.
